I have noticed that when I finish a Sketchup session and save the file that it is saved as a separate new file but that the old one still exists - however only the new file will open and we get this message if we try to open an older version
This seems strange to me and I cannot see the logic behind the decision. The old file is useless if you cannot open it so why not just overwrite it?
Also, on some occasions you may wish to be able to go back to an older version (to use as a template let’s say) and this would save having to undo everything to get back to an older point of the model - or indeed having to restart it as that may be the quicker option.
At one point I had 12 versions of the model in My Documents and kept them thinking they might well come in useful but then when I tried to open one, I couldn’t.
Is there a way to make all the older versions relevant and not just the last one?
renaming isn’t required, you can either use the “File > Open…” command with option “All Files (.)” resp. typing in the file name “*.skb”…
… or select the option “Select a program from a list of installed programs” from the dialog posted above and use the search button for selecting the “SketchUp(.exe)” in the SketchUp program folder. Which enables launching of resp. loading in running SketchUp by double-clicking SKB files.
Look under the File menu and notice SketchUp presents four save options.
Save a Copy As option creates a sequentially numbered copy of the file in it’s current state with each save.
Instead of cluttering your My Documents folder with individual model files, consider creating a folder for your models in My Documents.
Then, in SketchUp go to Window > Preferences > Files
There, you can tell SketchUp where to save to.
The problem with doing this is that you start to use BAK files as your working files and then you get backups of backups that are working files and everything gets really confused.
Personally I would re-name if you ever need to restore from a backup - it saves accidentally working from a backup file.
